Geological map of Kerkasha (1:40,000 scale) with Anagulu Prospect (red dashed ellipsoid in the southwest) and locations of Colonial Mines, Artisanal Mines & other Prospects
The primary control for Au-Cu mineralisation at Anagulu is the ~200m wide shear zone at the contact between the mafic volcaniclastics and the felsic metasediments (black dotted line).
Geology – Anagulu
Unexplained gravity anomalies AN-H1 & AN-H2 (white dashed ellipsoids) immediately to the northwest and sub parallel to the mafic volcaniclastic and the felsic metasediment contact:
Gravity anomalies (white dashed ellipsoids) on geology – Anagulu
Resistivity anomaly (white polygon) sub parallel to the mafic volcaniclastic and the felsic metasediment contact:
Resistivity anomaly (white polygon) with gravity anomalies and geology – Anagulu
Chargeability anomalies AT01 & AT02 (blue polygons) increasing in intensity from 100m vertical depth to 250m vertical depth (depth extent of survey) immediately to the northwest and southeast and sub parallel to, the mafic volcaniclastic and the felsic metasediment contact. The ATO1 chargeability anomaly is coincident with the two gravity anomalies (AN-H1 & AN-H2):

Coincident soil & rock chip anomalies for Au & Cu (yellow polygons 1 & 2) at surface over 2kms long immediately to the southeast and sub parallel to the mafic volcaniclastic and the felsic metasediment contact. Another smaller Au-Cu anomaly (yellow polygon 3) is starting to appear immediately northwest of the coincident gravity (AN-H2), resistivity and chargeability (AT-01) anomalies in the northeast of the Prospect:

The best zone of drilling to date (red ellipsoid) in coincident with:
- Anomalous Au-Cu in soil and rock chips (Area1)
- The AT-02 chargeability anomaly and
- Immediately southeast of the mafic volcaniclastic and the felsic metasediment contact:

Located 7kms due north of the Anagulu Prospect.

The Prospect sits bound by two generally north-south structures and has the same northeast orientation for mineralisation to the Anagulu Prospect.
Very significant Au results from rock chip sampling are located over an ~6km northeast trend (zone of interest) at the contact between a granodiorite and a mafic. Very high values for Au were also returned over a kilometre to the northwest of the contact, within the mafic.

Gold tail in dish from panning in Artisanal Area – Aburna
The Aburna Prospect was identified as very similar to the Anagulu Prospect from ‘Machine Learning’ (white spots over Anagulu Prospect in diagram below) and probabilistic modelling (thematic image in diagram below) of all our regional datasets (airborne magnetics, radiometrics, electromagnetics, Aster imagery, solid geology, structure, 35 element surface geochemistry). The probabilistic modelling was carried out in late 2018 and identified Aburna as prospective before our traditional geological prospecting identified it.

Intriguingly, the Machine learning has also identified a Prospect that has yet to be investigated that is ~5kms east of Anagulu and aligned in the same orientation.
Located in the northeast of the Kerkasha Project

Gossan & exhalate outcrops in the northeast linked with anomalous Cu-Au-Zn in soils (over ~3kms) to a malachite rich mafic-felsic contact in the southwest. The very impressive Cu-Au-Zn soil anomaly is larger than the Au-Cu soil anomaly over Anagulu Prospect and remains open to the southwest, northwest and northeast.
This Prospect has had no drilling on it to date.
The Tolegimja Prospect was identified as very similar to the Anagulu Prospect from ‘Machine Learning’ (white spots over Anagulu Prospect in diagram below) and probabilistic modelling (thematic image in diagram below) of all our regional datasets (airborne magnetics, radiometrics, electromagnetics, Aster imagery, solid geology, structure, 35 element surface geochemistry). The probabilistic modelling was carried out in late 2018 and identified Tolegimja as prospective before our traditional geological prospecting identified it.
